Abstract:
Due to the current lack of nuclear microsatellites (simple sequence repeats - SSRs) specifically developed for Pinus nigra, an important European coniferous species, we cross-species amplified 12 EST-SSRs (expressed sequence tagged SSRs) developed for other Pinus species in P. nigra in order to delineate loci which can be used for assessing levels of genetic diversity and genetic structuring in this species. We amplified these loci in individuals from seven populations from the central Balkans representing four recognized infraspecific taxa of P. nigra (ssp. nigra, var. gocensis, ssp. pallasiana, and var. banatica). Contrary to expectations on high transferability of EST-SSRs into related species, only three out of 12 tested loci were successfully amplified in P. nigra, but they displayed lack/low levels of polymorphism or generated multilocus amplification products. Thus, our estimates on levels of genetic diversity (HE = 0.183) and genetic differentiation (FST = 0.007) were based on variability of a single locus harboring four alleles only and they should be taken with cautions. Our study highlights the need for the development of high-resolution molecular markers, such as co-dominant genic or genomic SSRs or predominantly biallelic SNPs, or utilization of anonymous dominant markers, such as AFLPs, for genotyping in P. nigra.

Abstract:
With the estimated increase in global demand for food and over-reliance on staple food crops, the exploitation of agricultural biodiversity is important to address food security challenges. The aim of this study is to develop approaches to transfer major informational and physical resources developed in model plant and major crop species to resources poor crop species, using oil palm and Bambara groundnut as two exemplar crops. XSpecies (cross-species) approach, the core approach of the study, is described as the approach which uses microarrays developed for a given species to analyse another related species. The use of the XSpecies approach (here the cross-hybridisation of DNA from oil palm onto heterologous Affymetrix microarrays for Arabidopsis and rice), is the first experiment reported in oil palm and focused on a bulked segregant analysis of different shell-thicknesses for oil palm fruit. Primers design involved screening candidate probe-pairs filtered using PIGEONS software against oil palm transcriptome sequences generated using 454 sequencing technology. The results provided an insight into the effects of sequence divergence between oil palm and the reference species (Arabidopsis and rice) onto the power of detecting single feature polymorphism (SFPs) in oil palm, implying the importance of close association between studied and model plant/crop in XSpecies approach. The XSpecies approach coupled with genetical genomics was also tested within legumes, with Bambara groundnut as the query species compared to soybean as the resource rich species (20 Mya). A mild drought experiment, conducted in a controlled environment glasshouse, used an F5 segregating population derived from a controlled cross between DipC and Tiga Nicuru in Bambara groundnut. The cross-hybridisation of Bambara groundnut leaf RNA to the soybean GeneChip individual oligonucleotide probes resulted in a total of 1,531 of good quality gene expression markers (GEMs) on the basis of the differences in the hybridisation signal strength. The first ‘expression-based’ genetic map (GEM map) was constructed using 165 GEMs spanning 920.3 cM of Bambara groundnut genome. The first high density DNA-marker genetic map of 1,341.3 cM combining dominant DArT and co-dominant SNPs, developed using the DArT Seq approach, with additional pre-existing microarray-based DArT and SSR markers, was also developed in the F3 segregating population. Both maps were combined to form the first integrated map of 1,250.7 cM with 212 markers. Morphological differences and the rapid reduction in stomatal conductance observed within the F5 segregating population in the drought experiment provided trait data for a QTL analysis. The comprehensive QTL analysis in Bambara groundnut detected significant QTLs for morphological traits using GEM map, including internode length, peduncle length, pod number per plant, pod weight per plant, seed number per plant, seed weight per plant, 100-seed weight, shoot dry weight and harvest index across four linkage groups: LG1, LG2B, LG8B and LG11A. The loci controlling internode length and peduncle length were also consistently mapped to single marker on LG1 in DArTseq map using F3 segregating population, suggesting that these two traits are probably controlled by single gene or two closely linked genes. Despite significant genotypes effects on stomatal conductance tested in ANOVA analysis, no major QTLs were detected, suggesting the contributions of a number of small genetic effects to stomatal conductance. A preliminary homology search using the LG1 linkage group markers and associated gene models showed the ability to develop a framework for identification of candidate genes in Bambara groundnut relative to soybean. The present study also developed the resources for an eQTL analysis in a cross-species context. Translation from major and model plant species to underutilised and resource poor crops is critical to be able to develop many crop species with potential for future agriculture. This study examines some of the approaches which might be adopted and replicated in various underutilised crop species.

Full text
Abstract:
In areas where land is disturbed to extract energy resources such as coalbed methane, improper soil management may result in soils impaired by elevated salinity. The objectives of this study were to evaluate the emergence and growth of three native grass species (Pseudorogeneria spicata, Hesperostipa comata, and Pascopyrum smithii) as a function of i) soil salt content and matric potential, and ii) coversoil depth overlying a saline substrate. The first study consisted of nine treatments, combining three soil salinity levels (0.80, 5.0 and 11.0 dS/m) and three matric potential ranges (-0.1 to -1.0, -1.0 to -7.0, and less than -7.0 bars). Seedling emergence, plant height, aboveground biomass, and belowground biomass were significantly decreased by increasing soil salinity and decreasing soil moisture. A correlation analysis showed matric potential to be more significantly correlated to seedling emergence and growth than soil salinity. This resulted in large reductions in growth when soil moisture was decreased within a salinity treatment. Emergence for plants grown in elevated salinity increased as much as 26.7 % when moisture was high. At low soil moisture, elevated salinity resulted in emergence losses as high as 88.3 %. Losses in aboveground biomass ranged from 23.0 to 97.9 % at moderate salinity and 27.3 to 98.5% at high salinity. Results indicate that the impacts of elevated soil salinity are highly influenced by soil moisture. Irrigation will be an important factor in revegetation of saline soils. Also, investigators studying plant growth on saline soils must closely consider the impact of soil moisture on study results. For the second study, a substrate consisting of a mixture of soil and geologic stratum was salinized to an EC of 11.0 dS/m. Non-saline coversoil was applied on top of the saline substrate at depths of 0, 5, 10, 15, 30 and 45 centimeters. Aboveground and belowground biomasses were significantly greater with increased coversoil depth, with depths of 15, 30 and 45 cm producing similar results. Results suggest that coversoil is necessary to improve plant growth on a saline substrate, but applications of less than 45 cm may be adequate.

<p>The society is changing faster than ever and more and more business is actively seeking help with their organisation. The theory in business management of our time is making man and nature more and more distinct from each other, it celebrates the intellect and logical thinking but forgets about our biological legacy. This paper is arguments for a more natural way of management and compares mankind’s communication with other developed species communication with emphasis on business management. For a durable and long-term development of the society it takes a whole new way of thinking; If everyone is selfish, no one gets anything but if everyone gives everyone gets – to give is to receive.</p><p>In order to connect the theory with the reality interviews and an exercise was carried out on a company in Mälardalen. The interviews were analyzed with the aid of concentrating sentences in to categories in order to survey the activity in the corporation. The exercises were carried out as a statement of the positive effect of cooperation and a giving instead of an egoistic way of acting.</p><p>This paper is to be seen as a wake up call and inspiration for further research than as a psychological or scientific thesis.</p>

Hawthorne, Helen. "The least developed countries, the World Trade Organisation and the norm of special treatment." Thesis, City University London, 2011. http://openaccess.city.ac.uk/1120/.

Full text
Abstract:
This thesis examines the special treatment of the Least Developed Countries (LDCs) in the World Trade Organisation (WTO). The categorisation of the LDCs by the United Nations in 1971 not only created a new classification of counties, but also created an international norm of special treatment for these countries. The norm of special treatment for LDCs has, since then, slowly spread throughout the international system and has been institutionalised in many international organisations, including the WTO. Evidence of the institutionalisation of the norm within the WTO can be found in its founding documents and agreements, as well as in the Doha Development Agenda. This institutionalisation of the norm has meant that LDCs have been provided with special treatment in the trade regime, which is not provided to other categories of member. This thesis will trace the development and institutionalisation of the international norm of special treatment for LDCs and will focus specifically on its institutionalisation within the GATT/WTO. The thesis uses the concept of the norm lifecycle to demonstrate how the norm of special treatment for LDCs has grown in strength over time and become institutionalised, but has yet to be fully internalised. Through the use of case studies looking at accession, market access and cotton, it argues that the recent agency of the LDCs means that they can be seen as norm entrepreneurs helping to further the norm of special treatment by their appeals to it.

Full text
Abstract:
Abstract The introduction of species to new locations leads to novel competitive interactions between resident native and newly-arriving non-native species. The nature of these competitive interactions can influence the suitability of the environment for the survival, reproduction and spread of non-native plant species, and the impact those species have on native plant communities. Indeed, the large literature on competition among plants reflects its importance in shaping the composition of plant communities, including the invasion success of non-native species. While competition and invasion theory have historically developed in parallel, the increasing recognition of the synergism between the two themes has led to new insights into how non-native plant species invade native plant communities, and the impacts they have on those plant communities. This chapter provides an entry point into the aspects of competition theory that can help explain the success, dominance and impacts of invasive species. It focuses on resource competition, which arises wherever the resources necessary for establishment, survival, reproduction and spread are in limited supply. It highlights key hypotheses developed in invasion biology that relate to ideas of competition, outlines biotic and abiotic factors that influence the strength of competition and species' relative competitive abilities, and describes when and how competition between non-native and native plant species can influence invasion outcomes. Understanding the processes that influence the strength of competition between non-native and native plant species is a necessary step towards understanding the causes and consequences of biological invasions.

Abstract:
Abstract This chapter discusses the application of pangenomics for molecular breeding of wheat. Pangenomes can be used by both researchers and breeders alike to develop elite wheat cultivars through the discovery and integration of genetic variations associated with agronomically beneficial traits. By providing a reference that accommodates for variation in individuals, variants whose presence and/or absence control abiotic stress resistance and yield can be identified. This tool has only become more informative as more wheat varieties are sequenced, new sequencing approaches such as long-read sequencing and genome mapping are utilized, and tools for pangenomic analysis are developed. With pangenomics, variable genes from wild wheat relatives and related species can be used to optimize wheat molecular breeding and develop improved varieties tailored for the changing global environment.

Full text
Abstract:
Abstract Every organism on Earth, whether in natural or anthropogenic environments, is connected to a complex web of life, the famous 'entangled bank' coined by Darwin in 1859. Non-native species can integrate into local 'banks' by establishing novel associations with the resident species. In that context, network ecology has been an important tool to study the interactions of non-native species and the effects on recipient communities due to its ability to simultaneously investigate the assembly and disassembly of species interactions as well as their functional roles. Its visually appealing tools and relatively simple metrics gained momentum among scientists and are increasingly applied in different areas of ecology, from the more theoretical grounds to applied research on restoration and conservation. A network approach helps us to understand how plant invasions may or may not form novel species associations, how they change the structure of invaded communities, the outcomes for ecosystem functionality and, ultimately, the implications for the conservation of ecological interactions. Networks have been widely used on pollination studies, especially from temperate zones, unveiling their nested patterns and the mechanisms by which non-native plants integrate into local communities. Yet, very few papers have used network approaches to assess plant invasion effects in other systems such as plant-herbivore, plant-pathogen or seed-dispersal processes. Here we describe how joining network ecology with plant invasion biology started and how it has developed over the last few decades. We show the extent of its contribution, despite contradictory results and biases, to a better understanding of the role of non-native plant species in shaping community structure. Finally, we explore how it can be further improved to answer emerging questions.

Full text
Abstract:
AbstractIntroducing the main concepts of ERA Acute, this chapter describes the overall framework and purpose of the methodology. ERA Acute is a recently developed oil spill risk assessment (OSRA) methodology for quantification of oil spill impacts and risk (Environmental Risk Assessment, ERA). It covers four environmental compartments; sea surface (seabirds, turtles, marine mammals), water column (fish eggs/larvae), shoreline and seafloor (species and habitats) using continuous impact functions and introduces the Resource Damage Factor (RDF). The methodology depends on external oil spill modelling and input data related to the presence and vulnerability of Valued Ecosystem Components (VECs). ERA Acute is developed to provide an improvement over the currently used “MIRA” method on the Norwegian Continental Shelf (NCS) and is better suited for risk management, decision-making and analyses from screening studies to full environmental risk assessments.

As we shall see, while most scientists are happy to agree on the essentials, the answer to this question is far from straightforward. We then briefly discuss the range of ways new species can evolve, and provide evidence for these different pathways. Finally, following from our opening quotations, we ask a somewhat more abstract and philosophical question that brings together many of the separate threads we have introduced: why is life not composed of a single species? . . . What is a species? . . . The classification of organisms into species is so familiar that it is easy to accept without much critical thought. On reading ‘Tiger, tiger burning bright’, or headlines such as ‘Man bites Dog’, we have no problem envisaging who the main protagonists are. Mention a tiger, and one immediately thinks of a large cat with stripes. To most people, species are simply a collection of organisms with a given set of physical traits. All classification systems include elements of personal preference as to how one chooses to classify any group of objects (e.g. by shape, size, or colour). However, there is evidence that ‘species’ represent categories that are more consistent between observers than the various ways of sorting out one’s stamp collection. The Fore, a highland people of New Guinea, are perhaps best known in the western world for the devastating prion-based disease ‘Kuru’ that afflicted their population as a result of ritualized consumption of dead family members. However, the people have close links to their natural environment and a remarkably detailed system of classifying the larger animals they see around them. In an early study to test the degree to which species assignations are consistent among peoples with different backgrounds, Jared Diamond compared the Fore nomenclature with that developed by European taxonomists. Birds found regularly in the Fore territory were divided by the Fore into 110 distinct types, and by zoologists into 120 types, with an almost exact one-to-one correspondence between Fore ‘species’ and taxonomists’ ‘species’.

Abstract:
A multi-species solver for plasma at thermodynamical equilibrium is developed. A numerical scheme, based on Roe’s approximate Riemann solver, is implemented with some modification regarding averaged quantities. Treatments for perfect and real gas have been carried out. The real gas approach considers changes in the composition of the gas in local thermodynamics equilibrium assumptions. These models have been applied to the classical shock tube problem involving two different gases and air as a multi-species gas.

Abstract:
Uniform supply of volatile species to an active surface along with the oxidant flow to sustain the surface electrochemical reaction, and its effective cooling in an anode supported solid oxide fuel cell (SOFC) is modeled. Three-dimensional nonlinear partial differential governing equations for the conservation of mass, momentum, energy, species, and electrochemical kinetics for both the anode and cathode ducts for steady laminar, incompressible flow are solved computationally. A planar, tri-layer SOFC module, which consists of porous anode and cathode layers, solid electrolyte and rectangular flow ducts, is considered. The homogenous porous electrode layers are characterized by constant porosity, permeability, and thermal conductivity, and the fluid in these porous layers is considered to be in thermal equilibrium with the solid matrix. The computational results highlight the influence of fuel and oxidant flow duct aspect ratio and porous anode-layer depth on the friction factor and Nusselt number for typical electrochemical loads, and the consequent thermal signatures of the SOFC.

Abstract:
A novel modeling technique for fluid flow and species transport in very large scale microfluidic networks is developed with applications to massively parallelized microreactors. Very large scale integration (VLSI) of microfluidic circuits presents an attractive solution for many biological testing applications such as gene expression, DNA sequencing and drug screening, which require massive parallelization of reactions to increase throughput and decrease time-to-result. However, the design and modeling of VLSI microfluidics remains challenging with conventional 2D or 3D computational fluid dynamic (CFD) techniques due to the large computational resources required. Using simplified models is crucial to reduce simulation time on existing computational resources. Many microfluidic networks can be solved using resistance based networks similar to electrical circuits; however, simplified models for species transport (diffusion plus advection) in microfluidic networks has received much less attention. Here, we introduce a simplified model based on resistance network based modeling for flow dynamics and couple it with a one-dimensional discretization of the advection-diffusion transport equation. The developed model was validated against CFD simulations using ANSYS Fluent for a flow network consisting of a 4 by 4 array of microreactors. It showed good agreement with 2D CFD simulations with less than 6% error in total pressure drop across the network for channels with a length to width ratio of 10. The error was only 3% for a channel length to width ratio of 20. The developed model was then used to optimize the design of a 100-microreactors network used for high purity cyclical loading of reagents. The reactor configuration with a minimum cycle time for reagent loading and unloading and minimum operating pressure were evaluated with the code. In theory, the simulation can be scaled to much larger reactor arrays after further optimizations of the code and utilizing parallel processing.

Full text
Abstract:
AlN has attracted much attention in the past few years as a highly promising material for electronic and opto-electronic device applications. A halide vapor phase epitaxy (HVPE) system has been designed to grow high quality aluminum nitride layers at the growth rate up to 60 μm/h with the deposition temperature of 1000–1100°C and the pressure ranging of 5.5–760 Torr [1]. A 3-D numerical model that is capable of describing multi-component fluid flow, surface chemistry, conjugate heat transfer, and species transport has been developed to help in design and optimization of the epitaxy growth system. The effects of reactor pressure on heat transfer and reactive mixing process are studied. The effects of carrier gas (N2+H2) and reacting gas (AlCl3+NH3) flow rates on species mixing process and deposition uniformity have also been investigated. To achieve a uniform reactive species distribution above the substrate under a high carrier and reacting gases flow rate, a baffle is added in between the adduct boat and the substrate. Different baffle sizes, shapes and locations are tested to examine the optional conditions for the best uniformity.

Abstract:
In a fuel cell system the stack is strongly coupled with the main system components, among which the compressor is one of the most important. Malfunction of this auxiliary device (delay during peak power, low stoichiometry operation, emergency stop, etc) is directly responsible for bad oxygen distribution in the cathode (substoichiometry reactants feeding). This phenomenon is usually called oxygen starvation. In this study we want to identify the consequences of oxygen starvation on performance and durability of PEMFC stacks and more particularly on the current distribution along the cell. The oxygen concentration decreases along the channel and induces a change of the local electrochemical response; it means that the local current density on the cell is redistributed on the surface. This bad distribution of reactive gas (in a transient time or long time) decreases performance but may also have an effect on cathode degradation like carbon corrosion and platinum dissolution/oxidation. The current distribution along the cell is studied by two approaches (modeling and experiments). The local current is computed by measuring the local induced magnetic field and using Maxwell equations. The experiments are performed with a bi-cell stack developed by CEA with specific design for the magnetic sensors. The 3D model using serpentine bipolar plate meshing is adapted to dynamically compute the catalyst layer local conditions (local current, temperature, gases partial pressure, water activity). It is able to reproduce the conditions of low or high oxygen concentration in the cathode side.

Abstract:
Numerical simulation results are obtained for isotachophoresis (ITP) in two-dimensional straight michrochannel. This 2D ITP model is formulated based on finite volume schemes using 5 ionic components: one leader (LE), one terminator (TE), two samples (Sample A and B), and a counter ion electrolyte (C). Distinct net mobilities and diffusion coefficients are assigned to all ionic components, and an electric field is maintained along the channel to carry out the electrophoretic separation in microchannel. The computer model is developed to solve mass and charge conservation equations and to satisfy electro-neutrality condition in the system. Three different finite volume schemes, e.g. power-law, hybrid and upwind, are tested to obtain the best numerical solution of this electrophoretic problem. Numerical results show that power law scheme performs better; grid Peclet number up to 20 is acceptable for this nonlinear isotachophoresis. The effects of applied electric potential, ionic mobilities and initial distribution of samples on the separation behavior are also presented.

Abstract:
Abstract In this work, a chemical kinetic modeling study of the high-temperature ignition and laminar flame behavior of Tetrahydrofuran (THF), a promising second-generation transportation biofuel, is presented. Stochastic Species Elimination (SSE) model reduction approach (Eldeeb and Akih-Kumgeh, Proceedings of ASME Power Conference 2018) is implemented to develop multiple skeletal versions of a detailed chemical kinetic model of THF (Fenard et al., Combustion and Flame, 2018) based on ignition delay time simulations at various pressures and temperature ranges. The detailed THF model contains 467 species and 2390 reactions. The developed skeletal versions are combined into an overall reduced model of THF, consisting of 193 species and 1151 reactions. Ignition delay time simulations are performed using detailed and reduced models, with varying levels of agreement observed at most conditions. Sensitivity analysis is then performed to identify the most important reactions responsible for the observed performance of the reduced model. Reaction rate parameter modification is performed for such reactions in order to improve the agreement of detailed and reduced model predictions with literature experimental ignition data. The work contributes toward improved understanding and modeling of the oxidation kinetics of potential transportation biofuels, especially cyclic ethers.

Abstract:
The trees, developed green spaces, and natural areas within the City of Austin’s 400,882 acres will face direct and indirect impacts from a changing climate over the 21st century. This assessment evaluates the vulnerability of urban trees and natural and developed landscapes within the City Austin to a range of future climates. We synthesized and summarized information on the contemporary landscape, provided information on past climate trends, and illustrated a range of projected future climates. We used this information to inform models of habitat suitability for trees native to the area. Projected shifts in plant hardiness and heat zones were used to understand how less common native species, nonnative species, and cultivars may tolerate future conditions. We also assessed the adaptability of planted and naturally occurring trees to stressors that may not be accounted for in habitat suitability models such as drought, flooding, wind damage, and air pollution. The summary of the contemporary landscape identifies major stressors currently threatening trees and forests in Austin. Major current threats to the region’s urban forest include invasive species, pests and disease, and development. Austin has been warming at a rate of about 0.4°F per decade since measurements began in 1938 and temperature is expected to increase by 5 to 10°F by the end of this century compared to the most recent 30-year average. Both increases in heavy rain events and severe droughts are projected for the future, and the overall balance of precipitation and temperature may shift Austin’s climate to be more similar to the arid Southwest. Species distribution modeling of native trees suggests that suitable habitat may decrease for 14 primarily northern species, and increase for four more southern species. An analysis of tree species vulnerability that combines model projections, shifts in hardiness and heat zones, and adaptive capacity showed that only 3% of the trees estimated to be present in Austin based on the most recent Urban FIA estimate were considered to have low vulnerability in developed areas. Using a panel of local experts, we also assessed the vulnerability of developed and natural areas. All areas were rated as having moderate to moderate-high vulnerability, but the underlying factors driving that vulnerability differed by natural community and between East and West Austin. These projected changes in climate and their associated impacts and vulnerabilities will have important implications for urban forest management, including the planting and maintenance of street and park trees, management of natural areas, and long-term planning.

Full text
Abstract:
To assist US Army Corps of Engineers resource managers in monitoring for cyanobacteria bloom events, a laboratory method using hyperspectral imaging has been developed. This method enables the rapid detection of cyanobacteria in large volumes and has the potential to be transitioned to aerial platforms for field deployment. Prior to field data collection, validation of the technology in the laboratory using monocultures was needed. This report describes the development of the detection method using hyperspectral imaging and the stability/reliability of these signatures for identification purposes. Hyperspectral signatures of different cyanobacteria were compared to evaluate spectral deviations between genera to assess the feasibility of using this imaging method in the field. Algorithms were then developed to spectrally deconvolute mixtures of cyanobacteria to determine relative abundances of each species. Last, laboratory cultures of Microcystis aeruginosa and Anabaena sp. were subjected to varying macro (nitrate and phosphate) and micro-nutrient (iron and magnesium) stressors to establish the stability of signatures within each species. Based on the findings, hyperspectral imaging can be a valuable tool for the detection and monitoring of cyanobacteria. However, it should be used with caution and only during stages of active growth for accurate identification and limited interference owing to stress.

Full text
Abstract:
Blowing snow accounts for a large part of Illinois Department of Transportation’s total winter maintenance expenditures. This project aims to develop recommendations on the design and placement of living snow fences (LSFs) to minimize snowdrift on Illinois highways. The research team examined historical IDOT data for resource expenditures, conducted a literature review and survey of northern agencies, developed and validated a numerical model, field tested selected LSFs, and used a model to assist LSF design. Field testing revealed that the proper snow fence setback distance should consider the local prevailing winter weather conditions, and snow fences within the right-of-way could still be beneficial to agencies. A series of numerical simulations of flow around porous fences were performed using Flow-3D, a computational fluid dynamics software. The results of the simulations of the validated model were employed to develop design guidelines for siting LSFs on flat terrain and for those with mild slopes (&lt; 15° from horizontal). Guidance is provided for determining fence setback, wind characteristics, fence orientation, as well as fence height and porosity. Fences comprised of multiple rows are also addressed. For sites with embankments with steeper slopes, guidelines are provided that include a fence at the base and one or more fence on the embankment. The design procedure can use the available right-of-way at a site to determine the appropriate fence characteristics (e.g., height and porosity) to prevent snow deposition on the road. The procedure developed in this work provides an alternative that uses available setback to design the fence. This approach does not consider snow transport over an entire season and may be less effective in years with several large snowfall events, very large single events, or a sequence of small events with little snowmelt in between. However, this procedure is expected to be effective for more frequent snowfall events such as those that occurred over the field-monitoring period. Recommendations were made to facilitate the implementation of research results by IDOT. The recommendations include a proposed process flow for establishing LSFs for Illinois highways, LSF siting and design guidelines (along with a list of suitable plant species for LSFs), as well as other implementation considerations and identified research needs.

Abstract:
This special report summarizes the regional workshop held 24–26 April 2018 at the US Fish and Wildlife Service (USFWS) Ecological Services Office in Carlsbad, California on the importance of collaboration among federal, state, and nongovernmental agencies to facilitate the recovery of threatened and endangered species (TES). This workshop focused primarily on one species, the least Bell’s vireo (LBVI), and how to achieve full recovery and eventual delisting through agency partnerships. A major theme of the workshop was applying the Endangered Species Act (ESA) Section 7(a)(1) conservation planning process as a building block towards recovery of LBVI—as well as other threatened, endangered, and at-risk riparian species within the Southwest. The main objective of this workshop was to assemble an interagency and interdisciplinary group of wildlife biologists and managers to detail how the Section 7(a)(1) conservation planning approach, in consultation with the USFWS, can assist in the recovery of LBVI primarily on federal lands but also other public and private lands. Goals of this workshop were to (1) review Section 7(a)(1); (2) outline LBVI ecosystem processes, life history, threats, and conservation solutions; and (3) develop and organize agency commitments to collaborative conservation practices.

Full text
Abstract:
The U.S. national parks have experienced significant climate-change impacts and rapid, on-going changes are expected to continue. Despite the significant climate-change vulnerabilities facing parks, relatively few parks have conducted comprehensive climate-change vulnerability assessments, defined as assessments that synthesize vulnerability information from a wide range of sources, identify key climate-change impacts, and prioritize vulnerable park resources (Michalak et al. In review). In recognition that funding and planning capacity is limited, this project was initiated to identify geographies, parks, and issues that are high priorities for conducting climate-change vulnerability assessments (CCVA) and strategies to efficiently address the need for CCVAs across all U.S. National Park Service (NPS) park units (hereafter “parks”) and all resources. To help identify priority geographies and issues, we quantitatively assessed the relative magnitude of vulnerability factors potentially affecting park resources and values. We identified multiple vulnerability factors (e.g., temperature change, wildfire potential, number of at-risk species, etc.) and sought existing datasets that could be developed into indicators of these factors. To be included in the study, datasets had to be spatially explicit or already summarized for individual parks and provide consistent data for at least all parks within the contiguous U.S. (CONUS). The need for consistent data across such a large geographic extent limited the number of datasets that could be included, excluded some important drivers of climate-change vulnerability, and prevented adequate evaluation of some geographies. The lack of adequately-scaled data for many key vulnerability factors, such as freshwater flooding risks and increased storm activity, highlights the need for both data development and more detailed vulnerability assessments at local to regional scales where data for these factors may be available. In addition, most of the available data at this scale were related to climate-change exposures, with relatively little data available for factors associated with climate-change sensitivity or adaptive capacity. In particular, we lacked consistent data on the distribution or abundance of cultural resources or accessible data on infrastructure across all parks. We identified resource types, geographies, and critical vulnerability factors that lacked data for NPS’ consideration in addressing data gaps. Forty-seven indicators met our criteria, and these were combined into 21 climate-change vulnerability factors. Twenty-seven indicators representing 12 vulnerability factors addressed climate-change exposure (i.e., projected changes in climate conditions and impacts). A smaller number of indictors measured sensitivity (12 indicators representing 5 vulnerability factors). The sensitivity indicators often measured park or landscape characteristics which may make resources more or less responsive to climate changes (e.g., current air quality) as opposed to directly representing the sensitivity of specific resources within the park (e.g., a particular rare species or type of historical structure). Finally, 6 indicators representing 4 vulnerability factors measured external adaptive capacity for living resources (i.e., characteristics of the park and/or surrounding landscape which may facilitate or impede species adaptation to climate changes). We identified indicators relevant to three resource groups: terrestrial living, aquatic living (including living cultural resources such as culturally significant landscapes, plant, or animal species) and non-living resources (including infrastructure and non-living cultural resources such as historic buildings or archeological sites). We created separate indicator lists for each of these resource groups and analyzed them separately. To identify priority geographies within CONUS,...

Full text
Abstract:
This study was conducted to inventory, classify, and map soils and vegetation within the ecosystems of Katmai National Park and Preserve (KATM) using an ecological land survey (ELS) approach. The ecosystem classes identified in the ELS effort were mapped across the park, using an archive of Geo-graphic Information System (GIS) and Remote Sensing (RS) datasets pertaining to land cover, topography, surficial geology, and glacial history. The description and mapping of the landform-vegetation-soil relationships identified in the ELS work provides tools to support the design and implementation of future field- and RS-based studies, facilitates further analysis and contextualization of existing data, and will help inform natural resource management decisions. We collected information on the geomorphic, topographic, hydrologic, pedologic, and vegetation characteristics of ecosystems using a dataset of 724 field plots, of which 407 were sampled by ABR, Inc.—Environmental Research and Services (ABR) staff in 2016–2017, and 317 were from existing, ancillary datasets. ABR field plots were located along transects that were selected using a gradient-direct sampling scheme (Austin and Heligers 1989) to collect data for the range of ecological conditions present within KATM, and to provide the data needed to interpret ecosystem and soils development. The field plot dataset encompassed all of the major environmental gradients and landscape histories present in KATM. Individual state-factors (e.g., soil pH, slope aspect) and other ecosystem components (e.g., geomorphic unit, vegetation species composition and structure) were measured or categorized using standard classification systems developed for Alaska. We described and analyzed the hierarchical relationships among the ecosystem components to classify 92 Plot Ecotypes (local-scale ecosystems) that best partitioned the variation in soils, vegetation, and disturbance properties observed at the field plots. From the 92 Plot Ecotypes, we developed classifications of Map Ecotypes and Disturbance Landscapes that could be mapped across the park. Additionally, using an existing surficial geology map for KATM, we developed a map of Generalized Soil Texture by aggregating similar surficial geology classes into a reduced set of classes representing the predominant soil textures in each. We then intersected the Ecotype map with the General-ized Soil Texture Map in a GIS and aggregated combinations of Map Ecotypes with similar soils to derive and map Soil Landscapes and Soil Great Groups. The classification of Great Groups captures information on the soil as a whole, as opposed to the subgroup classification which focuses on the properties of specific horizons (Soil Survey Staff 1999). Of the 724 plots included in the Ecotype analysis, sufficient soils data for classifying soil subgroups was available for 467 plots. Soils from 8 orders of soil taxonomy were encountered during the field sampling: Alfisols (&lt;1% of the mapped area), Andisols (3%), Entisols (45%), Gelisols (&lt;1%), Histosols (12%), Inceptisols (22%), Mollisols (&lt;1%), and Spodosols (16%). Within these 8 Soil Orders, field plots corresponded to a total of 74 Soil Subgroups, the most common of which were Typic Cryaquents, Typic Cryorthents, Histic Cryaquepts, Vitrandic Cryorthents, and Typic Cryofluvents.

Full text
Abstract:
Recent advances in visual sensing technology have gained much attention in the field of bridge inspection and management. Coupled with advanced robotic systems, state-of-the-art visual sensors can be used to obtain accurate documentation of bridges without the need for any special equipment or traffic closure. The captured visual sensor data can be post-processed to gather meaningful information for the bridge structures and hence to support bridge inspection and management. However, state-of-the-practice data postprocessing approaches require substantial manual operations, which can be time-consuming and expensive. The main objective of this study is to develop methods and algorithms to automate the post-processing of the visual sensor data towards the extraction of three main categories of information: 1) object information such as object identity, shapes, and spatial relationships - a novel heuristic-based method is proposed to automate the detection and recognition of main structural elements of steel girder bridges in both terrestrial and unmanned aerial vehicle (UAV)-based laser scanning data. Domain knowledge on the geometric and topological constraints of the structural elements is modeled and utilized as heuristics to guide the search as well as to reject erroneous detection results. 2) structural damage information, such as damage locations and quantities - to support the assessment of damage associated with small deformations, an advanced crack assessment method is proposed to enable automated detection and quantification of concrete cracks in critical structural elements based on UAV-based visual sensor data. In terms of damage associated with large deformations, based on the surface normal-based method proposed in Guldur et al. (2014), a new algorithm is developed to enhance the robustness of damage assessment for structural elements with curved surfaces. 3) three-dimensional volumetric models - the object information extracted from the laser scanning data is exploited to create a complete geometric representation for each structural element. In addition, mesh generation algorithms are developed to automatically convert the geometric representations into conformal all-hexahedron finite element meshes, which can be finally assembled to create a finite element model of the entire bridge. To validate the effectiveness of the developed methods and algorithms, several field data collections have been conducted to collect both the visual sensor data and the physical measurements from experimental specimens and in-service bridges. The data were collected using both terrestrial laser scanners combined with images, and laser scanners and cameras mounted to unmanned aerial vehicles.
